Tiffen 138mm Letterbox Diopter +1/15mm (138LETTER15BX1) EX DEMO

Professional Cinematic Effects with the Tiffen 138mm Letterbox Diopter

The Tiffen 138mm Letterbox Diopter +1/15mm is a specialized optical tool designed for cinematographers looking to push the boundaries of traditional focus. Unlike standard diopters, the Letterbox configuration features a 15mm open slot in the center, flanked by +1 strength diopter glass. This unique design allows for sharp focus in the center of the frame while applying diopter effects to the top and bottom sections.

Creative Versatility and Control

Often described as the reverse of a Strip Diopter, this filter enables a wide range of experimental visual styles. By utilizing the dual-sided glass, users can achieve unique in-camera looks without the need for post-production manipulation.

• Varied Focus: Maintain clarity on a central subject while shifting focus planes elsewhere.
• Diffusion Effects: Soften specific areas of the frame for a dreamlike aesthetic.
• Double Imaging: Create complex, layered visuals directly through the lens.

Industry-Standard Build Quality

Constructed with Tiffen's legendary optical glass, this 138mm diopter fits seamlessly into professional matte boxes and filter trays. This specific unit is an Ex-Demo model, offering the same high-performance standards expected from Tiffen at an exceptional value. It is an ideal addition for rental houses or independent directors of photography seeking to expand their creative toolkit.
